A project with assistance from German experts was launched recently to give the Ngo Mon (South Gate) to the Imperial City located within the citadel of Hue in the namesake city in central Vietnam a ‘whitened’ look. As the structure’s walls have been blackened and covered with dirt, moss and fungus patches, the Hue Relics Preservation Center, in cooperation with Kärcher, a worldwide provider of cleaning technology, has decided to clean it using an eco-friendly and chemical-free method known as steam cleaning. The method includes a cleaning machine, which will heat the steam at boiling temperatures, and a special nozzle to increase pressure of the steam flow to 0.5-1 bar as it exits the pipe and hits the Ngo Mon’s walls.VNA Photo: Quốc Việt
